I looking to buy a new 13 sport with an intended use for a tender. I'm concerned with having to buy it with the Mercury outboard. I was thinking of getting it with a Honda 40 but find from the dealer that they only get it with the Mercury. Should I have a concern? Does anyone know of a dealer that will give it to me the way I want it?

I have the same boat (2002) with a Mercury 40hp 4 stroke EFI..It's a great package and engine..I wouldn't hesitate to buy the Mercury.

If Electronic Fuel Injection means anything at all, the Mercury is a better engine. The Honda has the old fashioned carburetor technology. How long has it been since 4-stroke auto engines were made with carbs?

My opinion doesn't count for much around here. Be that as it may, I concur. I have had experience with 3 Mercury four strokes; a 25 HP carberated, a 60 HP EFI, and now a 40 HP EFI. I like the EFI, the motor starts like a modern car. Just turn the key; no choking or need to advance the throttle.

P.S.

For 2004 swim ladders are an option on the Sport 130 and 150. Whaler is putting in some Whaleboard plates on the transom for swim ladders to be installed.

The 40 EFI Four stoke mercs are more yamaha than merc anyway.

Capt - You've got that one exactly backward. The 40 Merc EFI 4-stroke and 40 Yamaha powerheads are 100% Mercury, made in the good old USA. So are the 30's and the 60's. The Yamaha versions do not get the EFI technology, however.
The Yamaha 50 is built on a different block (I believe the older joint venture block) from the new Mercury 50, but also does not have EFI.

lhg, A chart/spreadsheet of the Yamaha/Mercury engines showing which company had the lead etc. would be interesting. I've owned a 1998 50HP Yamaha 2 Stroke and currently own a 2003 15HP Yamaha 2 stroke, 1976 4.5HP Mercury and now a 2004 90HP Mercury 4 Stroke. What you are saying is Yamaha and Mercury have had their hand in each one. Maybe not the old Iron Seahorse, but maybe. They have been busy together. Thanks for the background. Jim

I thought it was a joint venture? Where are yamahas built anyway? I love my 40 efi merc.

The original (first) Mercury/Yamaha 50Hp 4-strokes were the joint venture. I think the Yamaha 50 still uses this engine. But I think the new 30-60HP Mercury EFI's are all Mercury. Yamaha now uses the powerhead from the Mercury 30, 40 & 60 Mercs. Checking both manufacturers specs on these engines, you'll note the blocks are the same.

Conversely, I think the Mercury 75, 90 & 115's are basically Yamaha designs, although I have been told both companies manufacture their own.

The Mercury 225 is clearly Yamaha's 225, with some improvements in sound control by Mercury. I read that Mercury contracted to buy 4000 of these from Yamaha, directly from Yamaha of Japan, much to the dismay of the Yamaha of America people. I am wondering if Mercury will now give Yamaha a chance to buy 4000 of their new 250 HP I-6 4-strokes in exchange?

The two companies have been sharing 4-stroke technology for some time now, and I think Mercury helped Yamaha get started in the outboard business years ago.

Larry,

With regards to the 75, 90 and 115 are you talking just 4 stokes or 2 strokes as well?

Thanks,
Matt

Everything I have been discussing is 4-stroke technology. Except for similarities in lower unit design, I believe Yamaha's and Mercury's 2 strokes are unrelated. The Yamaha 70 & 90 2 stroke seems very similar to the famous OMC 3 cylinder engine.

Incidentally, the Honda 75 & 90 lower unit is (or was) purchased from Mercury and uses Mercury props.

I believe that some of the Tohatsu/Nissan larger outboards also use Mercury lower units. The 70/90 hp 3-cylinder units in particular. Some of my prop hardware came in Mercury boxes. The Merc lower units get around.

I'm still here.
Basically what I'm hearing is that I should not be concerned about the 40HP Mercury. I am a bit confused since the dealer told me that the powerheads were made by Yamaha and Mercury made the bottom portion. If some of the info I've read here is correct it may be the otherway around. I'll will say that I still do not like the idea that I can't buy the engine of my choice.

I have a 3 cylinder Yamaha 70 and except for the OMC style fuel line connector and the fact that it has 3 cylinders, it is not similar to the 3 cylinder OMC 70.

why can't you just order the boat and trailer you want without a motor, then just put the motor you want on it? i'm not saying this can be done but try it, see what happens.

You should ask Century Boat Company (owned by Yamaha) why you MUST take a Yamaha engine on their boats. I think they should offer Mercurys to those who want them.

Regarding the Mercury 4-stroke 40Hp EFI (and also the 30,50 & 60) your dealer is mis-informed. The engine is 100% Mercury, and Yamaha also buys this powerhead (and maybe manufactures it?) for their 4-stroke 40 (as they do with their 30 & 60 also). But Mercury doesn't give them the EFI part of the package.

Well, let me get this all straight in my head if that's possible. I've got a hull that's designed by Boston Whaler but owned by Brunswick Corp., a trailer that's made by EZ loader and a 90HP Mercury four stroke that's actually made by Yamaha but owned also by Brunswick who also owns Sea Ray as well as many others etc etc etc. Does anyone really know who owns what or who designed what? The main thing that matters to me is that I don't buy junk and also don't pay too much and I think Boston Whaler, Mercury as well as EZ loader have their own reputations at stake so I feel good about my '03 170 Montauk. No matter who's name is on something, the bottom line is will they stand behind it? Is it reasonable priced? Does it look good? There's a certain amount of risk for each and every purchase we make and everyone must decide for themselve what that level is. Sony is world renounded in the quality electronics world but they carry the shortest warranties in the business, why is that?

If someone whats to buy a Honda engine, then that's their right but the manufacturer has the final say and if it's in their best interest to offer what helps them then it makes sense. Mercure engines on Whalers helps Brunswick and it's not hard to figure out why they don't want to sell someone elses engine. What's the likely hood that Ford would be willing to put a Dodge Hemi engine in their trucks with the bone crushing reliability of a GM 1 ton automatic transmission with Michelin radial tires all from the factory? I'll give you the answer, 0%.

That's my 2 cents worth. Sorry for the ramble, I'm off my soap box.

Alan, I hope you find what you want somehow.
